Nilfisk IVB3 M Wet and Dry Vacuum Cleaner 30 Litre Plastic Sack Pack of 5
These are NOT the SAFETY BAGS for ASBESTOS
Neither are they the safety bags for ASBESTOS bags which are the IVB3 H Safety Dustbags
Nilfisk IVB3 M and the Nilfisk-Alto Attix 3 commercial wet and dry vacuum cleaner 30 litre plastic sack packet of 5 they also fit WAP and the Festo, Hilti, Makita and Stihl branded vacuum cleaners parts.
These are a pack of 5, open top plastic sack that may suit the vacuuming of wet debris. They are cheap, because not many people use them, so make sure they are what you want!
The disadvantage is they tend to wrap themselves around the filter cartridge, due to air getting between the container and the sack, because of the creases where it's trapped between the container and the vacuum motor head. But they're better than a black garbage bag as they actually fit on the inlet spout.
